Validity and reliability of Turkish version of the Brief Pain

Abstract

Objectives: The aim of this study was to evaluate the validity and reliability of the Turkish version of the Brief Pain Inventory-Short Form for patients with chronic nonmalignant pain.

Methods: An analytical design was used. A total of 192 patients were included in the study. A demographic questionnaire and the Brief Pain Inventory-Short Form were used to collect data. Content validity was assessed by experts and construct validity was tested using exploratory factor analysis. Reliability analyses estimated the internal consistency and test-retest reliability. Cronbach's alpha and the item-total correlations were calculated for the subscales to examine internal consistency.

Results: Exploratory factor analysis yielded 2 factors: pain severity and pain interference, which accounted for 68.81% of the total variance. The coefficient alpha of both subscales demonstrated good internal consistency. The item-total correlations of the scale ranged between 0.56 and 0.87. The test-retest reliability was r=0.774 for pain severity and r=0.808 for pain interference (p=0.001).

Conclusion: The Turkish version of the Brief Pain Inventory-Short Form is a valid and reliable instrument to assess chronic nonmalignant pain.
